Question

Ram can do a piece of work in 15 days. rahim is 50% more efficient than ram. the number of days rahim will take to do the same piece of work

Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Find the amount of work Ram can do in a day:

Ram can do the work in 15 day.

⇒ 1 day = 1/15 of the work

Find the amount of work Rahim can do in a day:

Rahim is 50% more efficient than Ram:

⇒ 50% extra = 1/2 x 1/15 = 1/30

⇒1 day = 1/15 + 1/30 = 1/10 of the work

.............................................................................................

Find the number of days Rahim need:

1/10 of the work = 1 day

10/10 of the work = 1 x 10 - 10 days

.............................................................................................

Answer: Rahim will take 10 days to do the work.
